How I can customize antd tab active bottom tab bar color

I want to change bottom tab bar color same as tab heading. I have tried several methods but unable to succeed.

My Code:

export default function OurPhilosophy() {

 return (
     <Container maxWidth="lg" className="our-philosophy">
         <h3 className="heading1">Our Philosophy</h3>

         <Demo />
     </Container>
 )
} 

const Demo = () => (
 <Tabs defaultActiveKey="1" size="large">
     <TabPane tab="Heading 1" key="1">
         "Content"
     </TabPane>
     <TabPane tab="Heading 2" key="2">
         "Content"
     </TabPane>
     <TabPane tab="Heading 3" key="3">
         "Content"
     </TabPane>
     <TabPane tab="Heading 4" key="4">
         "Content"
     </TabPane>
 </Tabs>
);
